The Breathing Window
Anyone familiar with/comment on the Breathing Window? Is it on the market?
Here is what they say:
“…the Breathing Window reduces ventilation running and heat-loss costs by 10kWh/m2.annum…”
This means comparative costs with other models and types of HRV’s.
” 95% lower running costs than always on ducted HRV.
50% lower ventilation heat losses than ducted HRV, only occupied areas are ventilated.
4 year payback compared with 40 years for a ducted system.
